Thermally insulating fixture

Abstract

A thermally insulating fixture includes a self-tapping screw, a fixed member mounted on the self-tapping screw, and a thermally insulating member wrapping the fixed member. The fixed member is provided with a first through hole. The thermally insulating member is provided with a second through hole and a positioning groove. The self-tapping screw extends through the second through hole of the thermally insulating member and the first through hole of the fixed member. A thermally insulating cover is mounted in the positioning groove and covers the self-tapping screw. The thermally insulating cover has a receiving space which receives the self-tapping screw. The thermally insulating cover has a positioning flange which is positioned in the positioning groove when the thermally insulating cover covers the head of the self-tapping screw.
